Effects of acceptance and commitment therapy on fatigue for patients with cancer and other chronic health conditions: A systematic review and meta-analysis

Acceptance and Commitment Therapy for Adults Living With Inflammatory Bowel Disease and Distress: A Randomized Controlled Trial

INTRODUCTION

The bidirectional relationship between disease activity and mental health in inflammatory bowel disease (IBD) has prompted investigations into the efficacy of psychotherapeutic interventions such as acceptance and commitment therapy (ACT) on biopsychosocial outcomes. We aimed to examine the efficacy of an ACT program (intervention) in comparison with a cognitive behavioral therapy-informed psychoeducation program (active control) for individuals with IBD and coexistent psychological distress. Both programs were delivered online through a hybrid format (i.e., therapist-led and participant-led sessions).

METHODS

A total of 120 adults with IBD were randomized to either the intervention (N = 61) or active control groups (N = 59). Efficacy was determined using linear mixed models for group differences, in rate of changes in study outcomes, between baseline, postintervention, and 3-month follow-up.

RESULTS

The primary outcome health-related quality of life significantly improved in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to postintervention ( t [190] = 2.15, P = 0.033) in favor of the intervention group with a medium effect size (β = 0.41, mean difference = 0.07, 95% confidence interval 0.01-0.12, P = 0.014). Similarly, the secondary outcome Crohn's disease activity significantly reduced in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to 3-month follow-up ( t [90] = -2.40, P = 0.018) in favor of the intervention group with a large effect size (β = -0.77, mean difference = -9.43, 95% confidence interval -13.72 to -5.13, P < 0.001) ( P = 0.014). Furthermore, when observing the rate of change in outcomes over time for the groups separately, anxiety symptoms and pain significantly improved in the intervention group only, and conversely, ulcerative colitis activity and stress symptoms significantly improved in the active control group only. All other outcomes (N = 14) significantly improved over time in both groups including IBD activity, gastrointestinal unhelpful thinking patterns, visceral anxiety, fatigue interference, fatigue severity, fatigue frequency, psychological inflexibility, self-efficacy, resilience, current health status, depression symptoms, IBD control, and pain catastrophizing; however, these changes were not significantly different between the groups.

DISCUSSION

Both programs were of benefit to people with IBD and distress. However, ACT offers a significant added benefit for health-related quality of life and self-reported Crohn's disease activity and may be a useful adjuvant therapy in integrated IBD care.

Connecting the dots: the role of fatigue in female infertility

Fatigue, an increasingly acknowledged symptom in various chronic diseases, has garnered heightened attention, during the medical era of bio-psycho-social model. Its persistence not only significantly compromises an individual's quality of life but also correlates with chronic organ damage. Surprisingly, the intricate relationship between fatigue and female reproductive health, specifically infertility, remains largely unexplored. Our exploration into the existing body of evidence establishes a compelling link between fatigue with uterine and ovarian diseases, as well as conditions associated with infertility, such as rheumatism. This observation suggests a potentially pivotal role of fatigue in influencing overall female fertility. Furthermore, we propose a hypothetical mechanism elucidating the impact of fatigue on infertility from multiple perspectives, postulating that neuroendocrine, neurotransmitter, inflammatory immune, and mitochondrial dysfunction resulting from fatigue and its co-factors may further contribute to endocrine disorders, menstrual irregularities, and sexual dysfunction, ultimately leading to infertility. In addition to providing this comprehensive theoretical framework, we summarize anti-fatigue strategies and accentuate current knowledge gaps. By doing so, our aim is to offer novel insights, stimulate further research, and advance our understanding of the crucial interplay between fatigue and female reproductive health.

Dimensions of psychological flexibility and their significance in people with somatic symptoms: The 18-item Flexibility Index Test (FIT-18)

Psychological flexibility has been hypothesized to preserve health in bad times. We examined whether psychological flexibility as assessed with an abbreviated questionnaire, was indicated to preserve mental and physical health when having somatic symptoms. Principal axis factoring indicated that two dimensions best represented the 60-item Flexibility Index Test (FIT-60) questionnaire: "mindfulness and acceptance" (M&A) and "commitment and behavior change" (C&BC). We selected 18 items that best denoted these dimensions (FIT-18 questionnaire). Regression analyses in 2060 Dutch people with and without persistent somatic symptoms, indicated that the M&A dimension (β = 0.33, p < 0.001) and C&BC dimension (β = 0.09, p < 0.001) were additively associated with mental well-being, but not with physical functioning. Moreover, the M&A dimension was indicated to protect mental well-being when having more severe somatic symptoms (β = 0.11, p < 0.001). The observed differential associations with health suggest the significance for health of the two dimensions of psychological flexibility as assessed with the FIT-18 questionnaire.

Acceptance and commitment therapy reduces psychological distress in patients with cancer: a systematic review and meta-analysis of randomized controlled trials

Objective

This study aimed to systematically review and meta-analyze the clinical efficacy of acceptance and commitment therapy (ACT) in patients with cancer and psychological distress.

Methods

Randomized controlled trials (RCTs) from seven English electronic databases were systematically investigated from inception to 3 October 2023. A total of 16 RCTs from 6 countries with 711 participants were included in this study. Estimated pooled effect sizes (ESs) were calculated via inverse-variance random-effects or fixed-effects (I2 ≤ 50%) model and presented by standardized mean difference (SMD). Subgroup analyses were performed to reduce confounding factors and heterogeneity, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to evaluate the quality of the pooled ESs.

Results

The pooled ESs revealed that statistically significant improvements in anxiety [postintervention SMD = -0.41 (95% confidence interval (CI), -0.71, -0.11); p = 0.008; I2 = 65%; follow-up SMD = -0.37 (95% CI, -0.66, -0.08); p = 0.01; I2 = 29%], depression [postintervention SMD = -0.45 (95% CI, -0.63, -0.27); p < 0.001; I2 = 49%; follow-up SMD = -0.52 (95% CI, -0.77, -0.28); p < 0.001; I2 = 0%], and psychological flexibility [postintervention SMD = -0.81 (95% CI, -1.50, -0.11); p = 0.02; I2 = 84%; follow-up SMD = -0.71 (95% CI, -1.12, -0.31); p = 0.0006; I2 = 38%] in ACT-treated participants were observed compared to patients treated with control conditions. However, other outcomes, such as physical symptom alleviation, were not significantly associated.

Conclusion

The findings of this systematic review and meta-analysis suggest that ACT is associated with improvements in anxiety, depression, and psychological flexibility in patients with cancer.
